darek Posted October 23, 2006 Report Share Posted October 23, 2006 Hi I tried other versions of mandrake and mandriva before and never had this problem. I installed Mandriva 2007 and initially internet connection was fine then started to be very sluggish or not working at. Computer is connected to the router via ethernet cable and served by DHCP there is another computer connected via ethernet and wireless broadcasting. But I am interested in getting to work only one of them the one on ethernet. If I connect ethernet directly to cable modem everything is fast and fine but when it is pluged into router then the problems begin. No problem working undeer windows DHCP is set to distribute 3 numbers. Really appreciate your help guys. I did a search but answers I found were about wireless and ndis wrapper D.

ianw1974 Posted October 23, 2006 Report Share Posted October 23, 2006 Sounds like it could be a problem with ipv6. Disable ipv6 by adding this to /etc/modprobe.conf alias net-pf-10 off that might help, you can also do it in the browser, with Firefox, type "about:config" without the quotes, and then filter by ipv6 and set it to true to disable ipv6 within the browser.

darek Posted October 23, 2006 Author Report Share Posted October 23, 2006 Thanx I wil try that althought I did apply those fixes which were listed in 2007 errata to to turn off ipv6 and windows scaling but it didn't help, unless this fix works by different mechanism D.

ianw1974 Posted October 23, 2006 Report Share Posted October 23, 2006 There's a few ways to disable ipv6, which I wrote here: https://mandrivausers.org/index.php?act=ST&...=22&t=35816 problem is, I've read in some places on some that may or may not work. The easiest way is run the ifconfig command after the reboot, and if you're getting inet6 against it, then ipv6 hasn't been disabled. The alias command I listed always seems to work, but I included the others for completeness as is nice to know different ways of doing things :P Hope it sorts it.

darek Posted October 23, 2006 Author Report Share Posted October 23, 2006 What do you think about going the other way around and enabling ipv6 on a router I just started researching subject and looks like there are plenty of alternative firmware most popular one probably fro dd-wrt.com Quote Link to comment Share on other sites More sharing options...
ianw1974 Posted October 23, 2006 Report Share Posted October 23, 2006 In all honesty, there's no real reason to use ipv6 just yet. It's not taken off as such, although the support is there for it. You'd be best disabling for now, as and when it becomes more common-place, then it can be re-enabled where necessary. Quote Link to comment Share on other sites More sharing options...
darek Posted October 24, 2006 Author Report Share Posted October 24, 2006 (edited) Hi looks like I turned off ipv6 : [root@localhost darek]# ifconfig -a eth0 Link encap:Ethernet HWaddr xxxxxxxx inet addr:192.xxxxxxx Bcast:xxxxxxxxx Mask:xxxxxxxx.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:489 errors:0 dropped:0 overruns:0 frame:0 TX packets:592 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:100 RX bytes:413297 (403.6 KiB) TX bytes:76202 (74.4 KiB) Base address:0xac00 Memory:fe000000-fe020000 but the proble is still there [root@localhost darek]# route -n Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 192.xxxxxx 0.0.0.0 255.255.255.0 U 10 0 0 eth0 169.254.0.0 0.0.0.0 255.255.0.0 U 10 0 0 eth0 0.0.0.0 xxxxxxx 0.0.0.0 UG 10 0 0 eth0 I have no idea what else it might be D.

ianw1974 Posted October 24, 2006 Report Share Posted October 24, 2006 Can you ping the router OK? What's the contents of your /etc/resolv.conf? Quote Link to comment Share on other sites More sharing options...
darek Posted October 24, 2006 Author Report Share Posted October 24, 2006 (edited) Can you ping the router OK? What's the contents of your /etc/resolv.conf? Hi, pinging seems to be o'key [darek@localhost ~]$ ping xxxxxxxx PING xxxxxxxx) 56(84) bytes of data. 64 bytes from xxxxxxxx: icmp_seq=1 ttl=64 time=0.614 ms 64 bytes from xxxxxxxx: icmp_seq=2 ttl=64 time=0.612 ms 64 bytes from xxxxxxxx: icmp_seq=3 ttl=64 time=0.544 ms 64 bytes from xxxxxxxx: icmp_seq=4 ttl=64 time=0.604 ms 64 bytes from xxxxxxxx: icmp_seq=5 ttl=64 time=0.542 ms 64 bytes from xxxxxxxx: icmp_seq=6 ttl=64 time=0.599 ms 64 bytes from xxxxxxxx: icmp_seq=7 ttl=64 time=0.535 ms --- xxxxxxxxping statistics --- 7 packets transmitted, 7 received, 0% packet loss, time 6000ms rtt min/avg/max/mdev = 0.535/0.578/0.614/0.042 ms resolv.conf search xxxxxxxx. nameserver xxxxxxxx nameserver v problem seems to be very wierd I can conected to certain websites but not to the others then few minutes later I cannot access websites I could reach before, then after few minutes firefox is just spinning around.

ianw1974 Posted October 25, 2006 Report Share Posted October 25, 2006 I'd be tempted to edit the resolv.conf and remove that line: search hsd1.nk.comcast.net these search lines can slow down DNS, and you don't really need them anyway. I suggest remove that, make sure that the nameserver entries are correct, then try for example: host linux.org if it replies with ip addresses, then DNS is working fine, but remove that search line first. Hopefully you're using a static ip address, as if DHCP you might get the search line back again next time you reboot. Quote Link to comment Share on other sites More sharing options...
darek Posted October 26, 2006 Author Report Share Posted October 26, 2006 I had DHCP but switched to static IP. I removed search line and put two of my ISPs DNS servers which appeared to be most reliable. Internet connection is now working much better but stilll there are moments when I have to wait a while. Once again thanx a lot and I will keep on educating myself how to improve the connection D. Quote Link to comment Share on other sites More sharing options...
